Hi All,
I printed 3 items yesterday, and each time the print reached about 45mm tall the printer would lock up and Pronterface would show this error on the screen.;

There was no interventure from me. I'm slicing with Slic3r, running Pronterface and Marlin. I looked though all the software, and couldn't find anything that might be causing this. Has anyone else experienced this behavior?

I might be completely wrong, but isn't 'E' the extruder temperature? if it is, then your thermistor might be shorted out and the printer goes into safe mode?
